The archive Project is a read-only Project. There is no option in the left hand toolbar to create new issues or global issues, even for System Administrators, in an archive Project.
Cross-project copies into archive Projects by both escalations and from the Details page are no longer allowed. Archive Projects are not listed in the drop-down list of Projects.
Issues in the archive Project can be restored to the original Project individually or in a batch process. There is a Restore Archive button on the Details toolbar for individual Issues. Once clicked, you are asked to confirm your decision. After clicking OK, FootPrints moves the issue from the archive Project back to the original Project.
Batches of Issues can be restored from the archive Project’s Homepage using the Restore option in the Quick Action Checkbox dialog.
